Documentation Grafana Cloud Learn and build Visualize data Dashboards Variables Cross-dashboard variables

Unlike variables that are specific to the dashboard in which you build them, you can create cross-dashboard variables for use across multiple dashboards. These variables help ensure consistent naming across your organization and eliminate the need to re-create the same variables every time you add a new dashboard.

You can scope cross-dashboard variables in two ways:

• Globally: Available to all dashboards in the organization.
• By folder: Available only to the dashboards in the same folder as the variable.

The Dashboards > Variables page lists cross-dashboard variables, showing which ones are available globally or by folder. In the following image, there are variables in “Core metrics” and “Grafana Cloud” folders and then a number of variables that aren’t in any folders; these ones are global:

When you add cross-dashboard variables to a dashboard, only the ones that share the same scope as your dashboard are available for you to select.

For example, in the preceding image, there are two variables in the “Core metrics” folder. The following image shows a dashboard in the “Core metrics” folder. As a result, the variables in the “Core metrics” folder are available to that dashboard, as well as all the global variables:

Variables in other folders aren’t available to that dashboard.

Create cross-dashboard variables

To create cross-dashboard variables, follow these steps:

1. Navigate to Dashboards > Variables.

2. Click + New variable.

3. Set the following general variable properties:

   Expand table

   Option	Description
   Folder	Set the availability of the variable. To allow the variable to be used in all of the organization’s dashboards, select Dashboards.
   Variable type	Choose a variable type.
   Name	Enter a name for the variable.
   Label	(Optional) Enter the display name for the variable drop-down list. If you leave this empty, then the variable name is used.
   Description	(Optional) Enter a description of the variable. When you add a description, an info icon appears next to the variable name on the dashboard. Hover your cursor over the icon to display the description. Descriptions support links. You can use Markdown-style links like [link text](https://example.com), or paste bare URLs like https://example.com. Only http and https URLs render as clickable links—other protocols display as plain text.
   Display	Choose where the variable displays: Above dashboard: The variable drop-down list displays above the dashboard with the variable Name or Label value. This is the default. Above dashboard, label hidden: The variable drop-down list displays above the dashboard, but without showing the name of the variable. Controls menu: The variable displays in the dashboard controls menu instead of above the dashboard. The dashboard controls menu appears as a button in the dashboard toolbar. Hidden: No variable drop-down list displays on the dashboard.
